A SIMD optimized version of the WELL512a random algorithm.
|
||
|
|
|
||
|
|
For a detailed description of how the algorithm works, please see the following pages:

Benchmarking shows that the SSE2 implementation is generally about 2-3 times faster than
|
||
|
|
the C implementation by the original authors.
|
||
|
|
|
||
|
|
It requires a SSE2 capable CPU (i.e. Intel Pentium 4 or newer, AMD Athlon 64 or newer).

All the source code except WELL512a.cpp|h that contains the original implementation

are released under the BSD license which allows you to include this in any open
